Description

Covariant perturbation theory is used to construct the electromagnetic form-factors of bound systems in the Light-Front after the integration over k- (= k0-kz) component of the loop momentum is performed. The Light-Front formulation of the form-factors in the Breit-Frame in the limit of momentum transfer q+ = (q0+qz) vanishing is considered. In this limit, it is shown that a pair term survives and is responsible for restoring the covariance of the light-front current. (author)
